Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...

Some materials are so strange they seem to break the rules of reality itself. From ultra-thin graphene stronger than steel to theoretical matter that could bend space and time, scientists are pushing ...

Here’s what you’ll learn when you read this story: You may feel like you’re constantly shaping your reality—but it could actually be the other way around. According to theory, when we interact with ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
